Finally creates a block of code that will be executed after a try/catch block has completed and before the code following the try/catch block. The finally block will execute whether or not an exception is thrown. If an exception is thrown, the finally block will execute even if no catch statement matches the exception.

If you can't handle them locally then just having a try / finally block...

If you can't handle them locally then just having a try / finally block is perfectly reasonable - assuming there's some code you need to execute regardless of whether the method succeeded or not. read less
